The tool features a 3\/16 inch body diameter, a 5\/64 inch drill point diameter, and a 5\/64 inch drill point length. The 118-degree drill point angle and 60-degree included angle make this tool suited for accurate center drilling and countersinking in a single operation. At 3 inches overall length, it falls into the long-length category, providing added reach for setups where a standard-length tool may not clear the workpiece or fixture. Machinists and toolroom technicians use this style of tool on manual lathes, CNC lathes, and machining centers to spot-drill, center-drill, and chamfer hole entries before finish boring or tapping.\u003c\/p\u003e\u003cp\u003eThis combo drill countersink is designed for countersinking and center-drilling operations across a range of ferrous and non-ferrous materials. The cobalt construction improves heat and wear resistance compared to standard high-speed steel, making it a practical choice in production environments where tool longevity matters. The plain cutting edge style and double end type extend usable tool life by allowing the operator to flip the tool when one end wears. The bright finish means no coating to chip or flake into a workpiece, keeping the cutting surface consistent through the tool life.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction for improved heat resistance and extended tool life over standard high-speed steel\u003c\/li\u003e\n\u003cli\u003eDouble-end design doubles usable life by allowing the tool to be reversed when one end wears\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle for accurate spotting and center drilling\u003c\/li\u003e\n\u003cli\u003e60-degree included angle for standard countersink geometry\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish eliminates coating delamination concerns\u003c\/li\u003e\n\u003cli\u003eLong-length classification at 3 inches overall for added reach in restricted setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard production tool for use in any lathe, machining center, or drill press capable of accepting a round-shank combination drill countersink with a 3\/16 inch body diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and operated by machinists and toolroom technicians following standard machine shop practices. Secure the shank firmly in a properly sized collet or drill chuck before operation and verify runout before engaging the workpiece. Always shut down and de-energize the machine spindle before changing tooling.
